If you don't know the first thing about programming, and your past your deadline, you're already screwed. For all the basics on how these things work, you'll have to read the documentation, complete with plenty of examples on how they work. Some things are like building blocks, like the Timer controls, others are far more abstract, like loops. You must LEARN how to put them together to get them to do what you want. There is no set formula that will show you how to do it.

does any one know how to workaround the memory issues with the tree view web control.

First, your question really belongs in the ASP.NET forum[^] since it has nothing to do with Visual Basic .NET.
Second, what memory issues? How did you come acrossed these issues and what documentation do you have (links would help) that says this is an issue?

This morning I changed the PROJECT properties of a VB6 program I'm doing,
After that, when I try to execute it, it gives me the Error Message Box "Sub Main() doesn't exist...
Only problem is it gives the same error in all the other versions of the program I have, even the older versions which I haven't touched or changed
I got to give the project in today...
PLEASE HELP VERY URGENT...
THANKS

have you renamed any of the files in the project? chances are you just renamed the default startup object and therefore the project is now looking to start from Sub Main(). Since it doesn't exist it's throwing up the exception.
to fix, just go into the project properties and set the startup object to whatever form you want to be the application's main form.

What did you change in the project properties? Did you try making a new test project (like a blank Windows application with just an empty form) and seeing if that works?
Without knowing anything about your project, the only suggestion we can make is to recreate the project, place all the controls again, and copy and paste the code from your previous project into this one.

Thanks,
Now The project if started correctly starts from Globals(MODULES), which tells the first form to start.
It has a Sub_main().
So I tried to start it as
PROJECT TYPE:Active DLL
Startup Object:Sub Main
Now it gives the MsgBox " User-defined type not defined"
The thing is, I didn't change the code...
Just the Project Properties...
And even the old versions are giving me the same error..
I tried creating a New application (a simple button and TExt) and it works.
I would copy and paste everything but the project is to long...
And the bosses here are MAD...
Is there anything else I should try?

There's your problem. ActiveX .DLL's don't user a Main. In order for this to work, you'll have to convert the project back to an .EXE. You can't use a Main in any .DLL's.

That is totally and utterly incorrect. A DLL MUST have a public class that can be created by an external user. HOWEVER it can still have a Sub Main. If so, Sub Main defines the entry point to the DLL.
You can have two startup settings for a VB DLL:
None:
The public class Initialize event provides the DLL entry point and this is the first code to run.
Sub Main:
You still have to have a public class to instantiate the dll. However, if you define Sub Main as the start up object, what happens is:
1) Your external client creates an class object in the dll.
2) In response to the request for the class object the dll FIRST executes all the code in Sub Main.
3) The dll then fires the requested class's Initialize event and returns the class object reference to the caller.
Now, what you CANNOT have in a VB DLL is a form as a startup object. Your options are "None" and "Sub Main".

I have written a MDI in VB.NET which is working fine. I decided to put my own icon on the forms (top left), and this too worked fine on all the children forms.
The problem I have is that the parent form is not called form1 (the default) and as I understand it, when I set the icon the form1.resx file is still applying the icon to a form called form1, when it should be apllying it to whatever I renamed form1 to. This causes an error when I run the program. If I replace the form1.resx and the form1.VB file with backups I took just before I changed the icon, it all works fine (without the icon).
Can anyone tell me (in an idiot proof way!) what I need to change in the resx file to get it to work with the icon?
Thanks a million.

Are you changing the icon in the icon property within the property grid when in design mode for the form?
If you are I can't see how changing the name of the form will cause any problems... or am i missing your point?

Hi,
I think this code will fullfill your need.
'--- BEGIN
Private Btn As Button
Private y As Integer = 10, ID As Integer = 1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Btn = New Button()
Btn.Location = New Point(10, y)
Btn.Text = "Button" & ID.ToString
AddHandler Btn.Click, AddressOf Hai_Click
Me.ParentForm.Controls.Add(Btn)
y += Btn.Height
ID += 1
End Sub
Private Sub Hai_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
Dim C As Control = sender
MsgBox("Hello Friend....! U Have Selected " & C.Text, MsgBoxStyle.Information, "")
End Sub
'--- END

Hello,
I am writing a UserControl in VB.NET. The UserControl has a class called NotifyClass. I have one USB device and when this device is connected to PC, I am taking this event to call the NotifyClass. On the other side, I have application in VB.NET which also calls a method a function in UserControl to pass some input parameters and get the result back. In short I have two instances one which calls my OCX notifyClass and one which calls OCX to get results. But these two events takes place at different times and there is no communication between them. Can anyone explain me how to implement communication between these remote objects?
I look forward to your reply.
thanks/regards,

I am trying to figure out if VB.NET (or even VB6) is the best way to test for an existing instance of an application. Basically, I want the code to test (I assume in Processes) whether the application is already active, and if it is, not open a second instance. (Of course, if it is not already running, then the application should open). Can anyone steer me in the right direction?
